Central Interceptor Project to Start in May 2019

Ghella Abergeldie Joint Venture and Watercare signed the contract to construct the Central Interceptor, a $1.2 billion wastewater tunnel with associated infrastructure.

The largest wastewater project in New Zealand, the tunnel will stretch over 13 kilometres from Western Springs to the Māngere Wastewater Treatment Plant, collecting wastewater along the way via sewers and drop shafts. The Grey Lynn Tunnel, a 2-kilometre long extension has also been awarded to the JV as part of the construction contract. Mobilisation will start in May 2019 and the whole project is expected to be completed by 2025.

The project will greatly benefit Auckland and the community by providing additional wastewater capacity to accommodate the growing city and help reduce the volume of wastewater overflows, so that everyone can enjoy clean waterways, beaches and estuaries.

Ghella Abergeldie Joint Venture has over 150 years’ combined experience working on major water and wastewater projects and has successfully completed numerous projects of this scale across the world.

This contract reflects another important milestone in Abergeldie’s 25-year long history as a multi-disciplinary construction company that delivers complex infrastructure contracts across Australia and New Zealand.

Mick Boyle, Abergeldie CEO, said “this is exactly the type of project that suits Abergeldie. It is complex infrastructure that will help build a better community by providing the people of Auckland with a greatly improved environment.

Both Abergeldie and Ghella are family companies with similar cultures so we are delighted to be in this joint venture with them. The Ghella Abergeldie Joint Venture is also very much looking forward to working with Watercare, a valuable client that we feel we will be able to work with collaboratively to ensure the delivery of the Central Interceptor project will be a success on many levels.”
